SPINNING DEVICE AATD METHOD.

Application filed August 12, 1925. Serial No. 45,792;

Thisinvention is a novel spinning device and method, having to do withthe twisting and winding of yarns, including any librous materials orstrands such as cotton, wool, silk or artificial silk. The main objectof the present invention is to provide a means factors tending to limitthe speed; with this invention a speed of 12,000 R. P. M. or higher isattainable. Other objects are, to afford uniformity of twisting actionand therefore-abetter product, to eliminate the objection ofballooning-of the yarn between the supply or rollers and the windingpoint, and'to enable the same device to be used for winding upon tubesor spools of small The present tive advantages of various prior spinningmeans while eliminating the respective disadvantages thereof; it is suchthat it is readily adapted to' be applied to existing machines, toreplace the usual spinning devices. without alteration; and it issimple, durable and inexpensive.

Other objects and advantages of the present invention will be explainedin the here,

inafter following description or will be apparent to those conversantwith the subject. To the attainments of the" objects and advantagesreferred to the present invention consists in the novel spinningmechanism and method and the novel features of combination, arrangement,construction and operation herein described or illustrated.

In the accompanying drawings showing an illustrative embodiment of theinvention. F 1 is substantially a central vertical cross section ofsufiicient of the mechanism to enable the features of the presentinvention to be disclosed. Fig. 2 is a top plan view partly in sectiontaken on the line 2-2 of Fig. 1. Fig. 3 is a top plan view of the partsabove the line 2'2 of Fig. 1. Fig. 4. is a right-hand elevation of.certain details seen in Fig. 1.

Fig. a view similar to Fig. 3. showing a modified construction; andFigs. 6, 7 and inhib t I 8, correspondingwith Figs. 2, 3 and i, show thesaid modification.

In the following description there will first be described thestationary parts, among which is a central vertical rod about which thereceiving element, spool or tube is placed, the usual driven spindlebeing here} in dispensed with. Then will be described the positivelydriven elements of mechanism, including the revolving guide eyes; thenthe means for traversing these longitudinally of the cop or bobbin. Thenwill be described the loose or free runningpjarts which hold and controlthe tube and bobbin, which latter, with this invention, is actuatedsolely by the pull of the yarn, controlled by retarding means or drag tobe described. Finally will be described the lubricating system.

Rigidly secured to a frame part 10, usual to such machines, is shown anupright threaded socket piece 11, cupped at its upper end, and heldbelow the frame part by a nut 12. Held rigidly within the bore of thesocket piece by a screw 13 is sho-w'nan upright central post 143;. Thispost ata'n intermediate point is provided with a. section 15 of reduceddiameter forming an' annular oil recess, and above this is a fulldiameter section 16, then a reduced diameter section 17 formed with agroove 18-, above which is, a cupped upper extremity of the stationarypost. Instead of a driven or rotatable central spindle, with itsattendant disadvantages, this invention employs a fixed central rod 20,which forms a bearing and support for thespool, tube or other removablereceiving element. 1 The stationary rod 20 is brazedinto a flanged base'piece 2 1 which in turn is secured against rotation in the cuppedextremity 19 of the main post 14 by means of a. connecting screw 22.

Power maybe derived from afast running belt 24- operatingon a pulley 25having :abelt groove 26, and the remainder of the driven parts maycomprise the following. The driven pulley is provided or formed with adownwardly extending sleeve 27 which bears. and rotates'up on thesections 16 andlt of the interior fixedjpost. However, the portions 14and 16 may be replaced by sleeves of bearing metal. The bearing sleeve27- is shown as having a lower oil hole 281 and an upper oil hole 29whereby the oil vessel to be described mayfeed into the recess locatedbetween the bearing sections 1% and 16 of the main post.

The rotary pulley is shown as formed or provided with a rotary disk 83at its upper side. This rapidly driven part forms the lower of twoopposed rotary disks or rings, the upper one being the annular ring 34:,and these two members being interconnected by stiff rods 35. formingwith the ole rotary disk 33.

.The yarn is shown descending, in twisted cond tion, at a, from .theusual rollers or other, supply, then through the usual fixed 3 upperguide eye adjacent the rollers. The

. of the traverse frame.

twisted yarn (L is shown passing through a fast revolving-guide eye 40mounted directly on the rotary ring 34 at the upper end From 7 thispoint the yarn descends at Z2 in asubstantially vertical direction. Thedescribed arrangement is one of the valuable iteatures of the present111- vention. Owing to-the fixed length or dis tancebetween the yarnsupply. point and the guide eye 4O1the rate and degree oli twistlng isalways un form notwithstanding the traversing movement to be describedin lay ing the yarn upon the cop. The distance from. the supply to theguide eye 40 and the definite rate (itclriveii rotation of the guideeye, determine the degreeot twisting, whichthereby may be maintainedquite uniform. The yarn passes alternatelyaround thebars of the'eye 40,arranged to deliect the yarn and so impose enough drag to in sure. the.described action. Owing to the short length from the supply to the guideeye 40, which is on. the ring 34L, at the top of the device, and thehigher tension due to the high speed, the tendency to ballooning iseliminated. V i

From the guide eye 4-10 the yarn 5 passes downwardly to aguide eye 41,which is moved vertically, or longitudinally of the spool, during thewinding. The yarn at c passes from the eye 41 directly to the spool.

The ultimate form of the built-up cop or bobbinumay be as indicated atd. The

' twisted strands,,in a uniform condition as stated, arelaidlperipherally on the cop by the rotation of the guide eye .41, andwithout suffering any strain, so that the usrial troublesome breakage atthis point is practically eliminated. To an extent this action resemblesthe winding of a thread upon a spool manually by allowing the thread toslip through the thumb and fin er, which apply; a certain tension on thetiread, but without strain, as these move progressively around thespool, while the longitudinal traversing act-ion builds up the cop ofdesired iorm. The guide eye 41 is shown mounted on a small and lightcarriage or slider 42 whlch is capable of slidlng long1-.

tudinally on one of the traverse guides 35 to give the desiredtraversing motion. The slider 4-2 is shown as formed with a pair of cars43 drawn together by a screw 4-41 and serving as a clamp for a doublefinger 4,5 which straddles, and thus engages above and below, a suitabletraversing means,which may be the usual one consisting of a blocl; orplate 47 having a circular recess id-sun rounding the revolving parts,and suitably actuated in any wellknown manner tomove the slider andguide eye longitudinally of the spool while laying the yarn in the defsired form. p I y As stated, there is no driven spindle herein, but thespool and bobbin are arranged to be loose or free running, and areadvanced onlyby the pull ofthe yarn, but controlled by a suitableretarding means, which there by etlects a diiierentiation in speedsandin? sures both an effective twisting and a regular, tight winding of theyarn. Thus a base 51" of circular form isishown, above] which stands upa conical support forthe spool, tube or bobbin. .These two partssurround the central rod 20 andare loose or tree run ning, and bearlightly upon tlieflanged'base piece 21 which supports the central rod.In

order to keepthe parts in relation a holddown. finger 53 isshowninouutcd outhebase 51 and extending under the flange of the support21. V i

As a retarding-means to prevent the spool and bobbin rotating at thefull speed of the traversing frame I prefer to employ a plu- I rality ofwings53, in symmetrical relation,

these being shown mounted radially on the free running base 51, and'ofsuch size' and" shape that air resistance efliects a satisfactoryretarding of. the rotation. This wlng device or but-terflyis found to befairly uniform and satisfactory in operation, and the retarding effectcan. be of predetermined amount by selecting wings of proper size andarrangement. i I

The tube or spool 57 or other receiving element for the yarn is shownasslightly conical, as is usual in the art, the tuberesting snuglydownupon thei ree running base 51 and surrounding the conicaltubesupport 52. It is Oneadvantageofthe present inventionthat a tube ofthesmallest diameter can be usedand thebobbin wound satisifactorily,irrespective of the distance from bobreadily be'used by means ofinterchangeable supporting members 51, 52.

Acircular oil vessel 60 is showrrsurroimd ing the'rotaiy sleeve 27, thisvessel having a 'cover'61 and a filling spout 62. *The'oil is 'ik'ept'inmotion by the rotation of the sleeve,

and it is found that pressure and flow throughholes 28, 29 are producedin a manner tokeep' the runi'iing surfaces well lubricated.

The described combination of elements gives "very satisfactory, uniformand efficient operation, permitting high speeds as stated. Many wellknown adjuncts are to be understood. Thus, for example, the yarn supplyrolls or other supply means may be regulated in a usual manner todetermine the rate of supply or paying out the untwisted yarn, therebyto control the complementary Winding and twisting operations and theoperative effect of the atmospheric retarding means.

The modification of Figs. -8 contains features not in Figs. 1-4. Thecentral fixed post 14 is fitted directly in the frame part by a rib 14and collars 14:, locked by a nut 12 The cupped upper end 19 of the postreceives the fixed rod 20 as in Fig. 1. The drive pulley is differentlyshaped, but comprises a sleeve 27 rotating on the central post, and oilholes 28 and a rotary disk 33- at the upper end. The top ring 34 isconnected to 38* by only two frame rods 35, of circular section, heldbelow in sockets 37 on 33. One of the rods 35 is grooved at 36 toreceive a pin 36 projecting from the slider 42. The oil vessel is at thefoot of post 1 F, and a wick 60 conveys the oil to the holes 28. Theremaining elements may be substantially as in Figs. 1-4.

In the two forms the central rod 20, which has been called non-driven,is shown fixed, but might be free, as is the holder or cone 52, forexample by removing the screw 22, or by brazing the rod, not to the base21, but to the cone 52; in which case the rod will turn with the coneand tube, resisted by the wing device.

Having thus described a preferred embodiment of the principles of myinvention, I desire to explain that many matters of design, arrangement,combination and detail may be variously modified without departing fromthe novel principles; therefore I do not intend to limit the inventionto such matters except to the extent set forth in the appended claims.
